Many modern pharmaceuticals contain fluorinated substituents, which are commonly synthesized using selective fluorinating reagents. Decafluorobiphenyl (DFBP) as a fluorinated linker is susceptible to nucleophilic attack. This nucleophilic reaction has been widely studied using
1 day ago Heterocyclic compound, also called heterocycle, any of a major class of organic chemical compounds characterized by the fact that some or all of the atoms in their molecules are joined in rings containing at least one atom of an element other than carbon (C). The cyclic part (from Greek kyklos, meaning “circle”) of heterocyclic indicates that at least one ring structure is present in such [A Special Symposium-in-Print: "Recent Advances in Medicinal Chemistry and Chemical Biology" Commemorating the 25th Anniversary Year for Bioorganic and Medicinal Chemistry Letters] "AlCl3-Catalyzed Ring-Expansion Cascades of Bicyclic Cyclobutenamides Involving Highly Strained Cis,Trans-Cycloheptadienone Intermediates."

Abstract: In recent years a number of compounds containing bis-spiroacetal systems have been ?. The synthesis of bicyclic molecules containing guanidinium subunits, such as (Scheme 22), are of considerable interest due to the wide range of biological activities presented by this family of natural products (see Section ).In one of the first biomimetic studies toward ptylomycalin A, a series of polycyclic compounds have been prepared through an intermediate 1-imino /bicyclic-molecule.
Thiazole moiety-containing compounds invention present an extensive range of applications in medicinal chemistry such as antibiotics, bacteriostatics, CNS regulants to high selling diuretics .
Thiazole framework has established wide application in drug growth for the treatment of hypertension [ 65 ], inflammation [ 66 ] and HIV 2 days ago Identical systems connected by a single bond Such compounds are defined by the prefixes bi- tert- quater- etc., according to the number of systems, and The 3,5-dimethylanilide group is considered an efficient π-donor structure in π-donor-HPLC chiral stationary phases having an amino acid as chiral moiety .The enantioselectivity of such chiral stationary phases can be particularly remarkable for certain analytes when this amino acid is L-proline .From these observations we have developed a simple method for synthesizing N-dodecanoyl-L usually more complex, while the reactivity of the non-aromatic systems is not too different from the usual non-cyclic derivatives.
Thus, most books on heterocyclic chemistry are mainly devoted to the reactivity of aromatic compounds. Tables – indicate models of the heterocyclic derivatives described in these :// The chemistry of heterocycles has always been an essential and growing area of organic chemistry. As such, the European Journal of Organic Chemistry and the Asian Journal of Organic Chemistry are publishing a global special issue on the occasion of the 27th International Society of Heterocyclic Chemistry (ISHC) Congress, which will be held in Kyoto, Japan, from September 1 to 6, (ISSN) This chapter covers bi- and tricyclic ring systems, highlighting recent development in the chemistry of bicyclic 6–6 systems containing one bridgehead nitrogen atom and one extra heteroatom and The Journal of Organic Chemistry.

Combining experimental and theoretical studies, we propose that the olefin promotes a Rh(III) intermediate to undergo oxidative addition into the O–N bond to form a Rh(V) nitrenoid species and subsequently
